Scope of standard 1.1 This practice covers the sampling of all grades of steel, both cast and wrought, and all types (grades) of cast irons and blast furnace iron for chemical and spectrochemical determination of composition. This practice is similar to ISO 14284. 1.2 This practice is divided into the following sections.SectionsRequirements for Sampling and Sample Preparation6General6.1Sample6.2Selection of a Sample6.3Preparation of a Sample6.4Liquid Iron for Steelmaking and Pig Iron Production7General7.1Spoon Sampling7.2Probe Sampling7.3Preparation of a Sample for Analysis7.4Liquid Iron for Cast Iron Production8General8.1Spoon Sampling8.2Probe Sampling8.3Preparation of a Sample for Analysis8.4Sampling and Sample Preparation for the Determination of8.5 Oxygen and HydrogenLiquid Steel for Steel Production9General9.1Probe Sampling9.2Spoon Sampling9.3Preparation of a Sample for Analysis9.4Sampling and Sample Preparation for the Determination9.5 of OxygenSampling and Sample Preparation for the Determination9.6 of HydrogenPig Irons10General10.1Increment Sampling10.2Preparation of a Sample for Analysis10.3Cast Iron Products11General11.1Sampling and Sample Preparation11.2SectionsSteel Products12General12.1Selection of a Laboratory Sample or a Sample for12.2 Analysis from a Cast ProductSelection of a Laboratory Sample or a Sample for12.3 Analysis from a Wrought ProductPreparation of a Sample for Analysis12.4Sampling of Leaded Steel12.5Sampling and Sample Preparation for the Determination12.6 of OxygenSampling and Sample Preparation for the Determination12.7 of HydrogenKeywords13AnnexesSampling Probes for Use with Liquid Iron and SteelAnnex A1Sampling Probes for Use with Liquid Steel for theAnnex A2 Determination of Hydrogen1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific statements, see 6.4.3.5, 9.4.4.3, and 12.5.1 as well as Section 5.
